UNITED STATES PATENT OFFICE.,

MILES PETTET, OF VEL'LINGTON, ONTARIO, CANADA.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 336,259, dated February 16, 1886. Application filed August 26, 1885, Serial No. 175,384. (No model.)

To @ZZ whom, it may concern,.-

Be it known that I, MILES PETTET, of Wellington, in the county of Prince Edward, in the Province of Ontario, in the Dominion of Canada, have invented certain new and useful Improvements in Car-Couplings; and I do hereby declare that the following is a full, clear, and exact description of the same.

The object of my invention is to couple cars automatically after prior adjustment of the coupling-pin, and to support the link horizon tally in the drawhead to effect coupling.

My invention consists of a draw-head provided with a post having an arm projecting through the end of the cnr-truck, and a coupling-pin hung on the end of the arm, so that when the drawhcad is forcedinward the arm will leave the pin, and the pin will drop into the link to effect coupling; also, in a link having a central cross-bar provided with a prop to bear within the mouth of the draw-head to support the link in horizontal position for coupling automatically.

Figure l is a longitudinal vertical section oftwo draw-heads approaching` coupling, showing my improvements. Fig. 2 is a top view ot' one of the draw-heads. Fig. 3 is a plan View of my improved link, and Fig. 4 is an elevation of the coupling-pin.

A is a portion of the car-truck or car, and B the draw-head, provided with the usual spring, C, whereby the draw-head will have the ordinary endwise movement when two draw-heads come together in coupling.

D is a post,secured to the drawhcad intermediate of the spring and mouth ot' the drawhead, and provided with a horizontal arm, D,

which passes loosely through a boss, E, on the end of the car-truck. The outer end of the arm slightly with the pin-hole in the draw-head when the draw-head is in a normal position, the projection being sutlicient to hang thereon the coupling-pin J, which is provided with a suitable eye. In such position the point of the pin enters the pin-hole, so that when two drawheads come together they will be forced end wise, and the outer end of arm D will be drawn into the boss, thereby leaving the pin, which immediately drops and secures the link which had previously been adjusted in the opposite draw head, and ett'ects coupling. The arm may, if desired, be provided with a screw, E, entering post D, to regulate the length ol' projection on which to hang the coupling-pin.

The coupling-link G has a crossbar, G', on which bar is hung a prop, H, to support the link horizontally in the draw-head when the pin is in the link by the prop standing within the mouth of the d raw-head, to ett'ect coupling ofthe link with the draw-head ofthe an neXing car.

I claim as my inventionl. The combination, with the draw-head B, ofthe post and arm D D and boss E, for hanging a couplingpin, J, and releasing the same by an endwise movement of the drawhead, as set forth.

2. The coupling link G, near its middle, and H, as set forth.

G, having a cross-bar, provided with aprop,
